NAME
SRC/crscl.f

SYNOPSIS

  Functions/Subroutines
subroutine crscl (n, a, x, incx)
CRSCL multiplies a vector by the reciprocal of a real scalar.

Function/Subroutine Documentation

  subroutine crscl (integer n, complex a, complex, dimension( * ) x, integer incx)

CRSCL multiplies a vector by the reciprocal of a real scalar.

Purpose:

    !>
    !> CRSCL multiplies an n-element complex vector x by the complex scalar
    !> 1/a.  This is done without overflow or underflow as long as
    !> the final result x/a does not overflow or underflow.
    !>

Parameters
    N

    !>          N is INTEGER
    !>          The number of components of the vector x.
    !>

    A

    !>          A is COMPLEX
    !>          The scalar a which is used to divide each component of x.
    !>          A must not be 0, or the subroutine will divide by zero.
    !>

    X

    !>          X is COMPLEX array, dimension
    !>                         (1+(N-1)*abs(INCX))
    !>          The n-element vector x.
    !>

    INCX

    !>          INCX is INTEGER
    !>          The increment between successive values of the vector X.
    !>          > 0:  X(1) = X(1) and X(1+(i-1)*INCX) = x(i),     1< i<= n
